Google AdWords is the service that places advertisements in a column to the right of Google search results. Narconon seems to use AdWords, so I have taken a look at the rules which Google AdWord customers are subject to.

People who visit a lot of Scientology and Narconon-related sites (including critical ones) are more likely to be served these advertisements so it might be worth knowing how to recognise a vulnerable one, and make a complaint about it.
